                  product description:

                  I. purpose and scope of use of pneumatic vacuum butterfly valve

                  GIQ series pneumatic vacuum butterfly valves are used to open or block airflow in a vacuum system of 1.3×10-5 ~ 3×105Pa.

                  GIQ series pneumatic vacuum butterfly valve main performance:

                  ● leakage rate: ≤1.3× 10-9pa.m3 /S;

                  ● applicable pressure range: 1.3× 10-5pa ~ 3×105Pa;

                  Working temperature: fluororubber -25℃ ~ +150℃;

                  Installation location: arbitrary;

                  ● air source pressure: 0.4-0.6mpa;

                  ● pressure difference on both sides of the valve plate has nothing to do with valve opening and closing;

                  ● life: ≥ 10,000 times.
